Specicaton of Letters Patent.

Patented Feb. 26, 1907.

To LZZ whom, it may concern:

Beit known that I, EDWARD M. IIEYLMAN, of Janesville, lisconsin, have invented a Cultivator, of which the following is a specification.

My present invention relates to cultivators of the wheeled type adapted to be drawn by horses and to be operated either in sitting or walking position.

In this invention I aim to improve on former constructions, iirst, by providing an improved method of guiding the shovel-gangs, whereby they are held as closely as possible to the growing plants without regard to irl regularity in the rows; second, by providing means for simultaneously raising the gangs and throwing` back the center of support for the cultivator by the moving of a single handle, thereby preventing the tongue of the cultivator from rising over the horses necks when the gangs are raised, and, third, by providing improved means for yieldingly supporting the shields which protect the plants from 4the shovels.

My invention also embodies an improved articulation between the shovel-gangs and the frame, which can be constructed more cheaply than in previous forms, while ottering superior advantages and facilities for adjustment, and secondary constructions and combinations, which will be more particularly described hereinafter and embodied in the claims.

In Vthe accompanying drawings in illustration ot my invention, Figure 1 is a plan view. Fig. 2 is a side view from the right. Fig. 3 is a sectional elevation on a longitudinal plane through the machine. Fig. 4 is a transverse section through the main arch of the machine-that is, on the line 4 of Fig. 1 4looking to the rear-a part being sectioned on the aXis ofthe front operating-shaft. rThe seat and seat-frame and the right-hand end of the rear operating-shaft, with the mechanism carried thereby, are here omitted for clearness sake. Fig. 5 is a transverse sectional' elevation through the axis of the wheels-that is, on the line 5, Fig. 1, looking to the rear. Figs. 6 and 7 are respectively a side elevation and a plan view of my improved articulation iior the shovel-gangs. Fig. 8 is a reverse plan view of the hinged pivot-bearing thereof. Fig. 9 is a side view of the treadle guide mechanism on an enlarged scale. Fig. 10 is a vertical sectional i elevation through the shaft thereof. Fig. l1 is a side elevation, on a large scale, of the details of the gang raising and adjusting mechanism. Fig. 12 is a vertical section of the same through the axis of the rear operatingshaft. Fig. 13 is a plan view of the same. F ig.' 14 is a perspective view of the washer on the end of the transverse operating-shaft. Fig. 15 is a perspective view of the hub of the hand-lever. Fig. 16 is a transverse section through the rear frame-casting on the line y of Fig. 12 g and Figs. 17 and 13 are side views at right angles to one another of the swivelpin for the spreader, the latter view showing it in place in the socket.

In these drawings every part is always designated by the same reference letter or nppmeral, and certain accessory parts which are common in cnltivators and form no part ot my present invention are omitted for the sake ot clearness.

The trame of the apparatus comprises the draft-pole 11, a pair of longittdinal framebars 12 on opposite sides thereof spaced apart, as shown, and having their forward ends bro'. ght together and bolted to the sides of the pole, as shown at 13, a main arch 14, which is secured to the pole by a U-bolt 11a at the center Vand to the longitudinal bars 12 by means of castings 15, and hub-castings 16, seclred by bolts 16EL to the rear ends of the longitpdinal bars. To these parts may be added the seat-traine, composed of a pair ot longitudinal bars 17, which are pivoted on bolts 13, srpported in downwardly and rearwardly extending l; gs 19, projecting from the castings 16, the bars 17 being bent parallel to one another at their rear ends and secired together by bolts 17 a, carrying spacingsleeves 17h. Between the bolts 17 a is sec-.red the seat 2O by means of a bolt 2Oa and a cross-block 2Gb. The seat-frame ttprns about the pivot-bolts 18, so that it may be thrown r pwardly and forwardly when ont of use-that is, when the machine is being tsed for a hand-ctltivator, in which case handles 21 (shown in dotted lines in Fig. 3) may be attached to the shovel-gangs for g1' iding them; b-.pt this arrangement forms no part of my present invention.

The castings 16 have hubs 22, in which are pivoted cranked axles 23, which latter carry on their ends the wheels 24, the ends of the IOC axles 23 passing throigh the habs 22 and being conneeted by a tiibnlar spaoing-pieoe 25, receiving these ends. As will be seen troni Figs. 5, 11, 12, 13, and 16, the interior of the lribs 22 is cored opt to a diameter to reeeive the ends of the spacing-piece 25, and the hirb is split longitndinally on the inner side, as shown at 221, Figs. 4l and 16, and is provided with liigs 22, which receive a sqnareshank clamping-bolt 22C, which serves to elanip the spacer 25 rigidlyv in the hpb, and thus hold the tWo sides ot' the traine together. The

ends of the axles 23 project into the end of:

the piece 25 and oseillatel therein, being sfrpported on the onter end of the hpbs 22 by a semi-annular lng- 27, which is iforined, as shown, by an inwardl-tpri'ied Vllange or bead on the rpper hall of the lr lb 22, which projects a s'1licient distance bevond the lower half thereof to adrnit a collar 26 i1 nder the l1 g 27. r1`he collar is secured rigidlj,T in place on the axle 23 by a set-serew 26. T he spacing of the Wheels may be adjsted bv properlyY setting,- the set-screiv 25a on the axle 223, the latter being pnshed into the hnb 22 to the proper distance.

The niain areh 14 is horizontal along its top and is bent rectangp larljT downward at each sido, and its extremities are bent rectangnlarly o ,tivard to lo 'in axle-arnis 2S, all as clearljT shown in Fig. The castings 15 have knee-soeliets 29, receiving the angles ot the inain arch, and are sec-red thereto by means of ti-bolts 30. Each casting 15 has 'further a grooved .0' 15a on its veppoi side .receiving the longitzeinal bar 12, Which is seerred in place therein by a bolt 15b. Eaeh piece 15 has also a hnb 31, in which rotates a sq-are shaft or axle 32, passingI across the iront oll the machine parallel to the niain arch and jnst behind the saine. This axle being of rectangular section is not jozrnaled directly in the habs 31; bpit it has clainped to each end a downwardljghextending rock-arm 33, Which carries a journal-boss 34, t1 rning Within the hub 31, as shown in Fig. 1, and on the right of Fig. 4. To each ioclr-arni 233 is connected at its lower end by a pivot-bolt 35 a link 36, Whose other end is connected vwith a pivot-piece 37, clamped to the vertical portion of the axle 23 bv a U-bolt 3 t irill be understood that this link connection is present on both sides of the inachine, where/bjT both axles are tiLrned sinn',ltaneonsl;T when the shaft 32 is rotated. The roelr-arin 33 on the right, however, diil'ers frein that on the left in having a soelet-piece 39 thereon, either cast integral therewith or secrv red separateljT to the shalt 32, and in this soelret is fixed, by ineans of a set-screw 40, the end of a bent lever 41, which extends baeliwardljT over the axle 23 and has on its rear end a handle L12 in position to be operated Vtroni the z eat 20. 1t will be observed that bfi7 raising` and lowering the handle L12 the linlrworl; is

Above the p ivo a guide post or projection 74, which. passes through a hole in the lever 68, and said post has coiled around it a spring 78, which being under compression acts to hold the lever 71 away from the handle 72 and the lower end thereof in engagement with the teeth 58.

The sector-arm 57 is provided with a snug 58a at one end thereof, which forms an abutment for the lugs to prevent the lever 68 from being turned so far back as to run cli the sector-arm, and a similar lug might be provided in the opposite end but for the fact that it would thenbe impossible to assemble the parts together, since the lugs 70 hook over the inner edge of the secttr-arm. l therefore may provide other means fer limiting the swing of the lever 68 in a forward direction, consisting of a washer or plate 66, mounted on the end of the shaft 53 and llaving va snug 66LL projecting from its inner side, said Washer having a central square aperture 66h, which lits the shaft to prevent the washer from turning thereon. rlhe outer margin of the hub 68ALL of the lever 68, as best shown in Fig. 15, is notched out at 68b through an arc whose length is such that the ends of said notclr abut against the snug 66" when the lever 68 is in its two eXtreme pesitions on the respective ends of the sector-arm 57 The shaft 53 projects beyond the washer 66 far enough to admit a linchpin 59 in a hole on the end thereof, which holds the shaft 58 and the parts carried thereby in place. Each hand-lever 68 has a forwardly-projecting arm 75, provided with a hook 76 on its end engaging one of the links of a chain 77, whose lower end is connected with the corresponding shovel-gang though the medium of a spring 79, and a horizontally-projecting arm 80, which, as best seen from Fig. 9, has one end 80a bent downwardly and turning in a socket 81, secured cn one of the frame-bars of the shovel-gang, and the other end of the bar 80 is provided with an eye 80h, with which is connected the lower end of the spring 79. rlhe object ofthe pivoted member 80 is to enable the shovel-gang to swing from side to side without being sensibly raised cr increasing the extension of the spring 79, which would happen if the latter were connected directly to the shovel-gang.

Each shovel-gang consists of three longitudinal frame-bars 106 107 108, which diverge rearwardly, the bars 106 and 107 being secured teg-ether at their front ends to the universal joint, as will be described later, and the bar 108 being secured to the side of the bar 106. At their rear ends these bars are secured together at their proper spacing by braces 109 and 110. Each longitudinal bar iscurved downwardly at the rear end, as shown, and has secured thereto a shovel or share of any approved form, (herein designated 111, 112, and 118.)

The universal joint or articulation by which the shovel-gangs are connected with the machine-frame provides means whereby the shovel-gangs may be oscillated vertically about a horizontal pivot and swung laterally about a vertical pivot. While former cultivatcrs have been provided with a joint permitting of these movements, the joint or articulation herein shown is of a novel and irnproved ferm and constitutes an important element of my invention.

On each cf the axle-arms 28 of the main arch 14 is mounted a sleeve 82, which turns loosely thereon and has at its inner end a depending angle-arm 88, whose lower end 84 is leent at right angles in a horizontal direction and is forked to receive the eye of a springrcd 78, and is provided with a number of holes 85 to receive a pin connection 7 8EL therefor. The spring-rod 78 connects the-anglearm 88 with a coiled counterbalanoe-spring 86, whose upper end is connected to a rod 87, whose upper end passes through a hole in the casting 15 and is threaded to receive a nut rlhe spring 86 tends to turn the sleeve 82 in a direction so as to raise the shovelgang which is mounted thereon, it being understood that the tension of the spring is not quite sufficient in itself to raise the shovelgang, but takes a greater part of the weight thereof, so as to make it easier to raise and lower the same, 'while the tension of the spring may be adjusted by screwing up the nut 88 on the bolt 87 tothe proper extent. r1`he sleeve 82 has a longitudinal spline 89, and on this sleeve is clamped one member of the pivot-joint composed of two members 90 and 91. (See Figs. 6,7, and 8.) rIhe member 90 has a fixed jaw 92, which is grocved at 98 to receive the spline 89, and a pivoted jaw 94, turning about a pin 95, which is mounted in a lug cn the piece 90 and cooperating with the aw 92 to clamp the 'member 90 in any position on the sleeve 82, a bolt 96 being used for this purpose. The member 90ccmprises, as shown, an upright tube ocned at the ends 90a, which enter corresponding sockets in the upper end ofthe piece 91, and a pivoted piece 97 which turns about a bolt 98, mounted in a lug 99 on the piece 91, and is hold against lateral motion by a tongue 100, which proj ects into a longitudinal slot 101 of the piece 97. A bolt 102 passes through the tubular 'member 90and through holes 108 and 104 in the ccned ends cf the pieces 91 and 97, respectively, and thus secures the joint together firmly, yet in a manner to allow the piece 91 to oscilla/ie about the piece 90 as an axis. The hole 104, as shown in Fig. 8, is squared to receive the square mortised head of the bolt 102 and prevents it from turning relative to the pieces 91 and 97. The form cf articulation thusdescribed cil'ers advantages over the form previously used both in the ease of construction and of adjustment and in the manner of removing and replacing the IOO rog

IIE)

eaaoee same, because the gang can be disconnected by withdrawing either the bolt 96 or the bolt 102 and withdrawn from the machine without disturbing any other parts of the apparatus.

The piece 91 has on opposite sides thereof recesses or sockets 105, which receive the ends of the longitudinal bars 106 107, which form the front end of the gang-frame and are secured to the casting 91 by bolts 137.

On each ofthe longitudinal bars 108 of the f shovel-gangs is mounted a piece 114, which carries a bearing-hub n115, in which oscillates a short hollow shaft 116, carrying on the outer end thereof an upwardly-extending rock-arm 116 and a downwardly-extending rock-arm 1163. The shaft 116 projects beyond the bearing-hub on the inner end and has a squared taper end 116, over which fits the taper hub 127EL of a treadlclever 127, which extends rearwardly and carries on its end a treadle or stirrup 128 in position to be actuated by the foot of the operator sitting on the seat 20. The taper hub 127a is drawn tightly over the taper end 116C by means of a bolt 116, passing through the tubular shaft 116 and having a nut 116e on the threaded end thereof. The upwardly extending arm 116u carries a pivot-nut 118, which turns in an eye 118EL in the end of the arm 116a and is secured therein by means of a cap-screw 118). The nut 1.18 engages threads 117Ll on the end of a rod 117, which has on its other end an eye 121, engaging an eye 122 on the end of a laterally-extending bracket 120, which is secured to' flange-lugs 123 on the piece 90 by means of bolts 124. The effective length of the rod 117 may be adjusted by removing the pivot-nut 118 from its socket in the piece 116L and screwing it to the proper position on the rod 117.

To the arm 116b is connected a retractile coiled spring 125 under tension, whose rear end is secured to a bracket 126, bolted to the gang-frame at the rear end thereon in such manner that the tension of the spring acts to throw the arm 116a forwardly, and thereby to swing the gang-frame inwardly.

Vllhen the liana-lever 41 is raise l, it will be seen that the square shaft 32 is osclllate l, the 5' depenling arms 33 oscrllate il backwar ly, and the wheels 24 thrust slightly to the rear by the link connection 36, so as to move the center of support rearwar ly. At the same time the rock-arm 64 strikes the end of the slot 63 of the link 62 and draws the latter forward, thus turning the member 55 on the right, and through it the square shaft 53 anll. the member 55 on the op'oosite site. he turning of the members 55 causes in like manner the two hand-levers 68 to be thrown back and the hook 76 to be rase'l, which ac tion, by means of the connections 77, 70, anl S0, raises the respective gang-frames, and in this action the counterbalancing-spring 86 assists, because the gang-frames turn solid y with the sleeves 32 about the axle-arms 23 of the main arch. By reason of the slot 63 the rearward motion of the wheels takes place in part before the raising of the gangs begins, and thus the weight of the latter is not brought upon the frame until the center of support has been shifted, and there is consequently no tendency of the pole 11 to be thrown up above the horses necks. ll' shoull also be remembered that in this posi tion the wheel center is slightly behnu the center of the hubs 22, so that the lerer 11 ten'ls to be thrown up and requires to he pullegl down in order to lower the gangs, whlle when the gangs are lowerel the wheel center is slightly in advance of the eenl er olt the hubs 22, an/l the reaction tends, therefore, to throw the lever 41 downward, and thus it will be seen that the force exerlel upon the lever 41 is always in the cireetlon of eas'iest exertion by the oliver-#to wit, in the direction of pulling upwanl. when lhe lever is in its lowest position andA 'pullhg downwardly when the lever' in its rais-ea position.

The shovel-gangs are guidi l laterally hy means of the treales 123, for it will he seen that pressure upon one of these tren, les causes the arm 116IDL to osc-llate to the rear, an l. this draws the gang-frame laterally towarfl. the wheel 24, the frame in thfs ease turning about the vertical pivotebolt '102, anil when 'iznessure uxron the trea ,le 125ml 1s remove ,l the retractile spring 125 draws rae gang-frame back toward` the center gainY This construction is superior to olf` furnis not only in the fact that a lateral movement of the treale is pro Vucel by a vertical moreinent of the foot, which is easest for the op erator to exert, but also in the fact that the link 1.17 is .independent of the axlearrin 2N, consequently remove from the axle-arm along with the shovel-gang by removing the ,bolt 06, anil when the positron of the pfeee 00 is 'lnovably a "ljusteLl upon the sleeve 52 the link 117 A:loes not requfre separate a justment, as is the case in a former construetrni.

lf it be res're l to hol l the two shorelgangs at a uniform distanee from eaeh other, l employ a s'frea`er or gage co1n,;if""1g an archel bar 129, having a lui-all y ol: holes in its ons, in one of which. may he een necte la vot-bolt131,whfch kisses through the forke `i en 'l 132 of a swivel-'fun 133, wh eh latter has a shank 133"L fittiv in a soekel piece 134, secure l to one of the longlu lnal bars of the gang-fratrie. When the srreaf er is in nlace, the two gang-frames are 'hell a t a unfform distance, angl their position vor erne l by s'multaneous pressure upor. holh trea"les 128, excess of pressure on one aus ing the gangs to swlno in one direction a l excess of pressure on the other causing the gangs to swing in the other direction.

uIn my improved cultivator I employ a .shield 155, having arms 13o', pivoted on one of the bolts 13l, which connect the gangframe to the piece 91, and an overnung bracket 138 on the gang-frame forms a point of support for a chain 139 or other flexible connection connectei to a point on the sinela.

A pair of brace-bars 140 are preferably arrangea 'to connect the outer ends of une axlearms 28 with the castings 16 for riglriitys sake, being secured. at one end to collars 148 on tne former (which also holii the sleeves S2 in place) and at the other to lugs 14S) on the under side of the castings 16. tee hig. 11.) 'ln ere is herein shown also a craft mecnainsni, consisting of an arched equalizer 141, pivoted to the tongue by a bolt 142 and having vertically-depending arms 143, whose lower enxis are connectei to the collars 14S on the outer ends of the axle-arms 28 by links 144, said depending ends 143 having holes 145, 'in any of which may be connected the clev.ses 146, which form the means for attachment of the whiflletrees 147 'l`h' s craft mechanism, however, coes not form a part of my present invention. A trough or receptacle 150 'is secured to the inner sine of one of the longituiinal frame-bars 12 for holding tools.

lt is to be distinctly understood that l do not consider my invention conlined to the use of all the various features above eescribed nor to the specific forms of construction herein shown, but that some of said features may be omitted and others modifier in var ous ways, as will be readily understood by those skiilei in the art.
